What will be my JEE mains rank? Which are the colleges I may get admission for B.Tech with 41 marks in JEE mains?

Dear Sudhanshu,
Keeping in mind this year JEE (Main) paper analysis, last year cut offs and only your JEE Main marks (boards not included), some of the institutes you might get are:
Mizoram University, Aizawl, Spot Round
Shobhit University, Saharanpur, Spot Round
Amity University, Lucknow, Extra Spot Round
Dr. K.N. Modi University, Jaipur, Extra Spot Round
(The above is as per last years closing ranks and may vary this year)
For the list of institutes, you can refer to shiksha college predictor
